But he did at least have them correct when he tested the new battery

Now that would be interesting, the board is so power hungry it eats the cmos battery by the time it gets to the customer. Would have to make an external holder and hook a meter between the battery and board to see what the parasitic draw is with a good meter that can do milliamps
 
Now who do we know that has a few of these boards and perhaps the equipment to do so???  hrmm, someone needs to contact Buildzoid, sounds like something he would be into testing
 
note: I was actually thinking of bcavnaugh when joking about testing then thought of Buildzoid

My x299 seems fine, but I did not test the voltage on the battery...do I need a voltmeter to do that or I can see it in the bios?
I did have a checksum error when updated BIOS to 1.12 but then after all seemed fine

I wish I was a young as Buildzoid
Never heard of him before today.

Just received a X299 dark from EVGA and thought i would check the CMOS battery before doing a build
 
Battery was 0.01v so this is obviously still an ongoing issue

Confirmed that the battery that I removed was dead. Tested -40mV.

Tested -40mV
Was The Positive and Negative set correct?
Kind of to odd to see a Negative charge.

 
He did have the leads crossed -
 

 

Yes, thanks. I did have the leads crossed. In either case -40mV or 40mV, the battery was dead... 
 
 

Most car FOB keys use the same battery so if it come down to booting the motherboard or driving at lest you can boot :-)

side note -I found out my car can actually start with a dead  ( or missing ) FOB battery as there is a near field chip in the key
a bit like the chip you can inject into pets - ( you do have to place the key in a special spot)

Don't have time to post pictures but I got my X299 dark on Friday and finally got around to testing the battery today. The battery in the board was reading 146mv so I replaced it. I won't be doing a build with it until I can afford a CPU and RAM so I can check it in a few weeks and find out if the motherboard is draining the battery while in storage. The new battery tested at 3.24v before I put it in the board.

Thanks for the report. It will be interesting to see if there are any changes in voltage and perhaps recheck it again as you start the build

Be interesting if you can check the bag with Ohm meter setting
they are many types of bags  -anti-static, static-shielding, and static dissipative bags and the wrong type may have been used.
 
We were told in the old days NOT to run ( power up)   IC boards on a static bag but I think now the resistance is 1 meg ohm and not the old 10K ohms

A little off topic shenanigans  --
 
The fob portion of the keys are for unlocking the doors and that is a whole different section in the vehicles systems - door locks fall under body control modules
Transponder chip in the key signals the security system (Different manufacturers call it different things) that validates weather or not that key is authorized for either starter start command (CAS on BMW) or the vehicle will crank over but the ignition will not be signaled, or with VW / Audi it will start and run then the immobilizer system shuts down the vehicle within 30 seconds or so.
Older physical keys only had an antenna ring around the ignition switch - hence why if you had multiple keys on your key ring they could interfere with one another.
New key-less cars have 3 antennas
 
Now back to your regularly scheduled topic..

Adam can that information be gotten off of the box as a lot of people have the board in their system and would have to remove it to get the requested information?

For anyone who has a motherboard with a dead CMOS battery, please PM me the details of your motherboard. I will need the serial number and factory manufacturing number from the back of the motherboard. The serial number will be on a black sticker and the manufacturing sticker will be on a white sticker. This would help us greatly in figuring out why there have been a few cases of this as this is very atypical.

This is for EVGATech_Adam B - I can't send a PM because I haven't posted to the forums 10 times yet. I've been lurking for a long time.... :)

That being said, I've had the same issues as described with the CMOS battery and Documentation for the X299 Dark. I sent the below to the EVGA team and got a basic canned response. It was very frustrating to get this especially with all the research, time and energy was put in by GGTV-Jon and myself when building my first new gaming PC in 9 years.

Below is what I sent to EVGA Support. I did as they asked and used the "Complaints and Suggestion" form on the website.....and guess what? No response.

Good Morning,

I would like to provide some feedback about this motherboard and the issues I had in installing it on Saturday. While nothing below was a "deal breaker", it did cause some major frustration in setup and building of my new computer. Especially with the amount of money I spent on this project, you don't expect these kind of issues.

The first was your official documentation concerning support of M.2 devices in the PM2 slot. According to motherboard manual documentation on Page 20 (attached) - Item 13, it states that "This connector can utilize only PCIe/NVMe-based M.2 SSDs, SATA M.2, or Intel® Optane™ NVMe devices". This is not true. I had an issue where the motherboard could not detect the Samsung 860 (SATA M.2) that I installed in this slot (in the first slot, I installed a NVME drive and it was detected without issue. After some troubleshooting and google searches, I found a support post in your forums about this. According to your representative from EVGA, they stated that this slot ONLY supports NVME based drives and not SATA M.2. - Many people were pointing out the discrepancy in the manual but this was ignored by the staff person. They did not acknowledge it. Forum Link:  

Secondly, after we discovered my drive wasn't supported (removed that drive) we turned to troubleshoot the random CMOS errors we were getting on POST. Come to find out, the CMOS battery on my brand new motherboard was virtually dead. (see pictures of battery and meter test attached). This caused additional headaches as this is not expected on a brand new product that has a MSRP of $500.00. Sadly, the replacement of the CMOS battery required complete disassembly of the computer as the battery is located under the I/O plastic shroud area that is screwed into the bottom of the motherboard. (again additional frustration)

I've been a long time customer of EVGA (as you can see by my history) and these kind of issues are something that should not expect.

I hope you are able to forward this to the proper departments so this kind of frustration doesn't happen to someone else. I will also add that this experience did make me question my future support of EVGA and if I should recommend your products to others based on what I went through on Saturday.

Thank you,

The Response:

Hi Chase,

Thank you for the feedback and I apologize for the troubles. These are definitely concerns and I've passed them over to our Product Management team to address. If you wish to reach them directly in the future, please use our Complaints and Suggestions form here. The complaints/suggestions do not go unseen. I hope you enjoy the board going forward and continue to be an EVGA patron despite the recent challenges. Let us know if we can assist further in any way.

Regards,

1. bad batch of batteries.
   It is NOT common to have a totally dead  no voltage primary cell
 
2. the parts storage box that hold the battery cells  before placing in board may allow shorting.
    ( remember the stories about 9 volt batteries in pockets and shorting by pennies)
 
3. The stand by current drain on unpowered board may be higher than other motherboards.
(a powered board get 3.3 v from the power supply system )
 
A small paper shim in the battery socket is what I use to open a battery circuit to allow taking a micro amp current reading.
-- chewing gum paper is what we used out at sea :-)
 
4. shipping wrapping / packaging  causing a  slow loss of power
